STEAM-CONDENSERr Patented March 19, 1907.

To all whom it may concern: p

Be itknown that I, SOREN THURSTENSEN, a citizen of the United States, residing at Louisville, in the county of Jefierson and State of Kentucky, have invented a certain new and useful Improvement in Steam- Condensers, of which the following is a specification.

The object of the present invention is to secure a condenser that will prevent undue back pressure in exhaust-lines for engines and pumps and which at the same time will be strong, durable, easy of construction and which may be readily cleaned.

Another object of the nvention is to simplify the construction as much as possible by arranging the cylinders of the condenser one above the other and supporting the upper cylinders upon the lower bymeans of the connecting pipes or passages.

' The final object of the invention is to improve theconstruction of the condenser as a Whole and the individual parts thereof.

In the drawings, Figure A is an end elevation, partly broken away, of the condenserof the presentinvention; Fig. B, a side elevation, partly broken away, showing the connecting-passages Fig. C, an end elevation of a sli htly-modified form of construction; and Fig. a side elevation, partly broken away, of the same.

In the form of construction illustrated in Figs. A and B the condenser as a whole consists of upper, intermediate, and lower cylinders 1,2, and 3', respectively, although the invention is not intended to be limited to the employment of three cylinders, since any other number might be employed. As

shown, the cylinders are of equal length and of graduated diameter, the largest cylinder being at the bottom and the smallest at .the top. Each of the cylinders comprises a cylindrical wall 4 and flat heads 5 at each end of the cylinder. One of the end heads of the lowermost cylinder is provided with a screwthreaded bushing 6, which serves as a connection for the exhaustjeppe of the en ine or pump for admitting sft eam to the condenser.

One of the cylinder-heads of the upper cylinder is likewise providedwith apipe or opening 7 for maintaining an atmospheric pressure within the condenser and preventing the formation of a vacuum. The cylinders are arranged one above the other in a vertical line, and a space is left between each of the cylinders. The cylinders are supported by means of longitudinally-extending semicircular plates 8, which run inwardly toward one another, and said plates, in combination with end plates 9, provide intermediate chambers 10 between adjacent cylinders.

The cylinder -walls are provided with holes or perforations 11, opening into the intermediate chambers 10, and this arrangement establishes a line of communication from top to bottom of the condenser as a whole. At

the same time the curving walls of the inter I mediate chambers serve to provide a support for the two upper cylinders, the lower cylinder being supported in any suitable manner. As shown, the lower cylinder rests upon sills 12, to which it is secured and heldby means of braces 13 or in any othensuitable manner. Immediately above the top of the cylinder and extending from end to end thereof is a spra 'ng-pipe 14, supported above the cylinder y means of brackets 15, which pipe is provided with openings 16, adapted to spray the water uniformly along the top of the top cylinder. Water is admitted to the spraying-pipe through a funnel 17, located in the middle of the pipe, and the water of condensation is discharged from the condenser through drain-flanges 18. A swinging safety check-valve 19 is provided to prevent any excessive pressure from bursting the condenser.

The condenser of Figs. 0 and D is in all respects like that hitherto described, with the exception that in place of the continuous curved plates 8 and the continuous steamtight intermediate chambers 10 a plurality of necks 20 are provided, which aflord communication between the cylinders and serve to support one above the other.

The operation in either case is the same.

The steam entering through the opening 6.

the condenser is at all times essary, which simplifies the construction and other, the lowermost cylinder being provided w1 th a steam-inlet and the topmost cylinder "being 7 cumstances the pipe ,7, communicating with theatmosphere, will be sufficient to estabhsh' an equilibrium. In order to condense -Water of condensation, or, distilled water, flows down from one cylinder to the other chamber between adjacentcylinders, the

the lntermediate chamber, and a Water-dis- 1 charge pi e abovethe topmost cylinder for pipe or opening 7. 'The steam thus admitted will pass from one cylinder to the other through the openings 11 until it has filled all the cylinders. The provision of the safety check-valve prevents any sudden ab: normal increase in pressure from bursting the condenser, although in ordinary on the steam so admitted, water is poured into the funnel 17 and distributed through the perforated header-pipe 14, whence it falls upon the top of the upper cylinder and flows down over the walls of the cylinder in the form of thin film, cooling the surface of the cylinders, against the inner walls of which the condensing-steam is brought in contact.

and is discharged at the lowermost point. The presentmcthod of forming a condenser as .-a whole provides a large surface area over which the cooling-water can flow, so that condensation will'take place very rapidly. By supporting the cylinders one-above the other inthe manner indicated no additional supporting means will'be found neccylinders being provided with holes into' cooling t scribed.

3. A steam-condenser comprising a pluadjacent cylinders steam-tight intermediate chambers between adjacent cylinders, the cylinders being provided with holes opening into the intermediate chambers, and a wator-discharge pipeabove the topmost cylin-l der for cooling the condenser, substantially as described.

4. A steam-condenser comprising a plurality of cylinders placed one above the other and of substantially equal, length, and of graduatedfldiameter from bottom to top, connections affording communication between the cylinders and; serving to support the cylinders one above the other, and a water-discharge pipe located above the topmost cylinder for discharging water upon the osition to ,ilow down over the outside of said cylinder and thereafter over all of the cylinders of the condenser, substantially as described.

5. A steam-condenser comprising a plurality of cylinders placed one above the other and of substantially equal length, and of graduated diameter from bottom to top, connections affording communication between the cylinders and serving to support the cylinders one above the other, and a waterdischarge pipe extending from end to end of the topmost cylinder and provided with a plurality of perforations for spraying water onto the topmost cylinder, in posit-ion to flow down over the outside of said cylinder and thereafter over all of the cylinders of the condenser substantially as described.
